Buffy is in heaven and sees Spike crying over her, asks to be sent back

Well the title is actually all I remember of this story
I don't know if she remembers that she was the one that asked to be sent back, I think I remember that she doesn't know that at first and she's all upset that they took her out of heaven and then she remembers (someone helps her remember) that she was the one that asked to be sent back because she had feelings for Spike and she didn't want him crying over her death.

possibly "world on fire" and it's sequel "blood debt" by Addie Logan?

that's the one, thanks!
